Veritas Storage Foundation 5.1 SP1 Cluster File System Installation Guide (5900-1510, April 2011)

To verify the server-based I/O fencing configuration

Verify that the I/O fencing configuration was successful by running the

vxfenadm command.

For example, run the following command:

# vxfenadm -d

Note: For troubleshooting any server-based I/O fencing configuration issues,

refer to the Veritas Storage Foundation Cluster File System Administrator's

Guide.

Verify that I/O fencing is using the specified coordination points by running

the vxfenconfig command.

For example, run the following command:

# vxfenconfig -l

If the output displays single_cp=1, it indicates that the application cluster

uses a CP server as the single coordination point for server-based fencing.

Setting up non-SCSI3 fencing in virtual environments

manually

To manually set up I/O fencing in a non-SCSI-3 PR compliant setup

Configure I/O fencing in customized mode with only CP servers as

coordination points.

See “Setting up server-based I/O fencing manually” on page 169.

Make sure that the Storage Foundation Cluster File System cluster is online

and check that the fencing mode is customized.

# vxfenadm -d

Make sure that the cluster attribute UseFence is set to SCSI3.

# haclus -value UseFence

On each node, edit the /etc/vxenviron file as follows:

data_disk_fencing=off
